This example presents a horizontal bar chart of the top 10 most populous countries, using population data from a CSV file. The chart is built with React and D3 v5, rendering SVG elements directly. The code uses `scaleBand` for the categorical country axis and `scaleLinear` for the population values, with axes manually constructed via tick maps. Bars are drawn as `rect` elements within a translated group, with labels for both axes generated from the scales’ domains.
